* Date:    18 Feb 2002
* SUMMARY: Testing re.exec(str) when re.lastIndex is < 0 or > str.length
*
* Case 1: If re has the global flag set, then re(str) should be null
* Case 2: If re doesn't have this set, then re(str) should be unaffected
*
* See http://bugzilla.mozilla.org/show_bug.cgi?id=76717
*
*
* From the ECMA-262 Final spec:
*
* 15.10.6.2 RegExp.prototype.exec(string)
* Performs a regular expression match of string against the regular
* expression and returns an Array object containing the results of
* the match, or null if the string did not match.
*
* The string ToString(string) is searched for an occurrence of the
* regular expression pattern as follows:
*
* 1.  Let S be the value of ToString(string).
* 2.  Let length be the length of S.
* 3.  Let lastIndex be the value of the lastIndex property.
* 4.  Let i be the value of ToInteger(lastIndex).
* 5.  If the global property is false, let i = 0.
* 6.  If i < 0 or i > length then set lastIndex to 0 and return null.
* 7.  Call [[Match]], giving it the arguments S and i.
*     If [[Match]] returned failure, go to step 8;
*     otherwise let r be its State result and go to step 10.
* 8.  Let i = i+1.
* 9.  Go to step 6.
* 10. Let e be r's endIndex value.
* 11. If the global property is true, set lastIndex to e.
*
*          etc.
*
*
* So:
*
* A. If the global flag is not set, |lastIndex| is set to 0
*    before the match is attempted; thus the match is unaffected.
*
* B. If the global flag IS set and re.lastIndex is >= 0 and <= str.length,
*    |lastIndex| is incremented every time there is a match; not from
*    i to i+1, but from i to "endIndex" e:
*
*      e = (index of last input character matched so far by the pattern) + 1
*
*    The match is then attempted from this position in the string (Step 7).
*
* C. When the global flag IS set and re.lastIndex is < 0 or > str.length,
*    |lastIndex| is set to 0 and the match returns null.
*
*
* Note the |lastIndex| property is writeable, and may be set arbitrarily
* by the programmer - and we will do that below.
*
